Description

[Detailed Description of the Invention] [Industrial field of application] In this invention, after transporting a plurality of explosive blocks by a projectile, the explosive blocks are discharged and deployed in a pearl-like shape, The present invention relates to a minefield treatment device that detonates and blasts a minefield to dispose of it.

[Prior Art] As a conventional device of this type, there is, for example, a device shown in FIGS. 3 and 4. In the figure, reference numeral 1 is a flying body, and the flying body 1 is configured by arranging a rocket motor 3 around a flying body main body 2. The flying body 2 has a cylindrical outer cylinder 4, a front case 5 is attached to the head of the outer cylinder 4, and a rear case 6 is provided with a breaking bolt 7 at the rear.
It is installed at. Further, a total of four rocket motors 3 are arranged on the rear side of the flying body 2. Incidentally, reference numeral 8 in the figure is a tail.

A plurality of explosive blocks 10 and the like connected by connecting lines 9 are accommodated in the projecting body 2 having such a structure in a butted state.

The head of the explosive block 10 is attached to the forward base 11 by the connecting rope 9, and the forward base 11 is connected to the inner surface of the front case 5 (the head of the flying vehicle). Further, the last explosive block 10 is connected to the rear base 12, the parachute 13 and the rear case 6 by a connecting cable 9. Furthermore, the rear case 6 is moored by the braking cable 15 near the launch point. This braking rope
The length of 15 determines the range of the flying object 1.

In such a mine field processing device, a timer (not shown) starts to operate at the same time as launching the projectile 1 toward the target mine field. When the projectile 1 reaches the vicinity of the sky above the target point, the breaking bolt 7 receives the signal from the timer and breaks. As a result, the rear case 6 is disengaged, the parachute 13 is released and the umbrella is opened, and the connected body of the explosive block 10 is aerobically braked from the rear. By this braking force, this connected body is pulled out from the flying body main body 2 (see step (I) in FIG. 5).

Then, the connected body of the explosive block 10 receives the braking force from the parachute 13 and the propulsive force from the flying body 1 and is pulled from the front and back while continuing the inertial flight, so as shown in step (II) in FIG. Then, the explosive blocks 10 in front and rear are sequentially separated, and finally, they are deployed in a pearl-like shape via the connecting cord 9 as in step (III) of the same figure. When the developed system descends onto the mine field, the braking rope 15 extends and brakes the entire system, so that the explosive blocks 10 are aligned and landed in series. Here, by detonating the explosives in the explosive block 10, the buried land mines are attracted and processed.

An example of this type is disclosed in JP-A-62-213699.
There is one such as that described in the publication.

[Problems to be Solved by the Invention] However, in such a conventional one, since the connecting rope 9 is directly connected to the inner surface portion of the front case 5 of the flying body 2, The force pulling the explosive block 10 acts on the head portion of the flying object 1. When a tensile force acts on the leading part of the flying vehicle 1, the flying direction is easily changed by the force, and as a result, the initially set flying direction shifts, and the explosive block 10 lands at the target position. Therefore, there is a possibility that the minefield cannot be properly treated.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and a plurality of rocket motors are arranged on the outer periphery of a hollow flying body main body to form a flying body. Inside, a plurality of explosive blocks connected in series by a connecting cable are sequentially butted and accommodated, and the leading explosive block of the plurality of explosive blocks is connected to the inner surface of the head portion of the projectile body by a connecting cable. While connecting, the explosive block at the end is connected to the braking means, and within a predetermined time after the launch of the projectile, the connecting rope is pulled from the front and back by the propulsive force of the projectile and the braking force of the braking means. In a mine field treatment device configured to pull out the plurality of explosive blocks from the inside of the projectile body in a continuous shape, between the top explosive block and the projectile body top portion,
A holding plate is slidably arranged in the projectile body, the holding plate and the leading explosive block are connected by a connecting line, and the explosive block is pulled out from the projectile body. The land mine disposal device is characterized in that the holding plate is set so as to move to the rear side of the flying object, and further, stop means is provided for stopping when the holding plate moves to the rear side.

[Operation] According to such means, when a plurality of explosive blocks are released from the projectile body before the launched projectile reaches the target position, the holding plate inside the projectile body is accompanied by this. It moves to the side and is stopped at a predetermined position by the stop means.

Then, the explosive block is pulled from the rear side by the braking means via the connecting line, and at the same time, is pulled from the front side by the flying object.

The tensile force of the flying object acts on the holding plate that has moved to the rear side of the flying object.

Therefore, unlike the conventional case, the tensile force does not act on the head portion of the flying object and the tensile force acts on the rear side, so that the flight direction of the flying object is largely influenced by the direction in which the tensile force acts. Therefore, a stable flight direction can be obtained.

Therefore, the plurality of explosive blocks can be landed in a predetermined shape on the minefield in a pearl-like shape, so that the minefield can be exploded and properly processed.

[Embodiment] Hereinafter, the present invention will be described based on an embodiment.

1 and 2 are views showing an embodiment of the present invention.

In this description, the same members as those in the related art are designated by the same reference numerals.

First, the structure will be described. In the figure, reference numeral 1 is a flying body, and the flying body 1 is constructed by arranging a rocket motor 3 around a flying body main body 2. The flying body 2 has a cylindrical outer cylinder 4, and a front case 5 is provided at the head of the outer cylinder 4.
Is attached, and the rear case 6 is attached to the rear end by the breaking bolt 7. Further, a total of four rocket motors 3 are arranged on the rear side of the flying body 2. Incidentally, reference numeral 8 in the figure is a tail.

A plurality of explosive blocks 10 and the like connected by connecting lines 9 are accommodated in the projecting body 2 having such a structure in a butted state.

The first of these explosive blocks 10 is the connecting cable 9,
First, it is attached to the forward base 11, this forward base 11 is connected to the holding plate 21, and further, this holding plate
21 is connected to the inner surface of the front case 5 (the leading portion of the flying body).

Further, the last explosive block 10 is connected to the rear base 12, the parachute 13 and the rear case 6 by a connecting cable 9. Furthermore, the rear case 6 is moored by the braking cable 15 near the launch point. The length of the braking rope 15 determines the range of the flying object 1.

The holding plate 21 has a disk shape, a flange portion 22 is formed on the peripheral edge portion, and is set so as to slide inside the flying body 2. The connecting rope 9 between the holding plate 21 and the front case 5 is connected to the holding plate 21 when the holding plate 21 moves to the rearmost side in the flying body 2 as shown in FIG. The length is set to stop the slide, and constitutes a stopping means which is one of the constituent elements of the present invention.

The holding plate 21 does not necessarily have to be connected to the front case 5, and a projection or the like protruding toward the rear side of the inner surface of the flying body 2 may be provided to stop the sliding holding plate 21. it can.

Next, the operation will be described.

In such a mine field processing device, a timer (not shown) starts to operate at the same time as launching the projectile 1 toward the target mine field. When the projectile 1 reaches the vicinity of the sky above the target point, the breaking bolt 7 receives the signal from the timer and breaks. As a result, the rear case 6 is disengaged, the parachute 13 is released and the umbrella is opened, and the connected body of the explosive block 10 is aerobically braked from the rear. By this braking force, this connected body is pulled out from the flying body main body 2 (see step (I) in FIG. 5). When this is pulled out, the holding plate 21
As shown in FIG. 1, it slides inside the flying body 2 to the rear side and stops when the connecting cord 9 between the holding plate 21 and the front case 5 is fully extended.

In this state, the explosive block 10 is pulled from the rear side by the parachute 13 as a braking means, and is also pulled from the front side by the flying body 1. In this case, the holding plate 21
The connecting rope 9 between the front case 5 and the front case 5 passes through the center of the flying body 2, and the connecting rope 9 between the holding plate 21 and the forward base 11 is oblique to the flight direction of the flying body 1. Will be pulled to. Therefore, the tensile force in a direction different from the flying direction of the flying body 1 acts on the holding plate 21 that has moved to the rear side of the flying body 1.

As a result, unlike the prior art, the tensile force in a direction different from the flight direction does not act on the head portion of the flying body main body 2, but acts on the rear side. As a result, the flight direction of the flying object 1 is It is possible to obtain a stable flight direction without being greatly influenced by

Then, the connected body of the explosive block 10 receives the braking force from the parachute 13 and the propulsive force from the flying body 1 and is pulled from the front and back while continuing the inertial flight, so as shown in step (II) in FIG. Then, the explosive blocks 10 in front and rear are sequentially separated, and finally, they are deployed in a pearl-like shape via the connecting cord 9 as in step (III) of the same figure. When the developed system descends onto the mine field, the braking rope 15 extends and brakes the entire system, so that the explosive blocks 10 are aligned and land in series. This landing position can be landed at an accurate position by obtaining the stable flight direction as described above. Here, unlike the conventional method, the explosive charge is detonated so that the buried land mine is detonated and reliably treated.

[Effects of the Invention] As described above, according to the present invention, the holding plate is slidably disposed in the projectile body between the explosive block at the top and the projecting body main body. , The holding plate and the leading explosive block are connected by a connecting line, and the holding plate is set to move to the rear side of the projectile in a state where the explosive block is pulled out from the inside of the projectile body. Further, by providing a stopping means for stopping when the holding plate moves to the rear side, the explosive block can be landed at a predetermined position without the flight direction being greatly changed by the influence of the tensile force. Therefore, it has a practically useful effect that the minefield can be properly treated.
